  WRF_ARTICLE_SCREENS040 Non-modifiable rows are caused by locked nodes
  
  
  Cause:
  This error occurs when you try to modify or update article data in SAP (typically in Retail or Merchandise Management modules), but the system detects that certain nodes (data records or structures related to the article) are currently locked by another user or process.
